How many bantam eggs can fit?

In a little giant with no egg turner? I visted the website and it only says chicken eggs not bantam eggs? Are they the same as quail? I've never seen quail eggs. I've got everything up and running for my first ever hatch attempt and I've ordered eggs (I know!)

It has been a few year since I hatched bantam eggs. The eggs were tiny compare to a regular chicken egg but lager than a bobwhite quail. Some of the jumbo brown quail I had laid eggs almost as large as some of the smaller bantam eggs. I would guess on average 2 bantam eggs equal one regular chicken egg.
